【考案の詳細な説明】 本考案は例えばシャンパン或はウィスキー等を収納せる
容器の密栓に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hermetically sealed container for storing, for example, champagne or whiskey.

この種密栓において、古くから使用されて来たコルク製
にかわり合成樹脂製の密栓が多用される。In this type of closure, synthetic resin closures are often used instead of the cork closures that have been used for a long time.

該合成樹脂製密栓は有底筒状に本体を形成して上側端間

容器口部に対する蓋栓時の押圧力又は脱枠時の捩り力、

くなる欠点がある。The synthetic resin seal plug has a main body shaped like a cylinder with a bottom and an opening at the upper end. Since it is configured to be closed with a stopper lid that is a separate member,
Pressure force against the container mouth when closing the lid or twisting force when removing the frame,
Alternatively, since it is necessary to form the material with sufficient mechanical strength so as not to cause deformation etc. against the pulling force, the material can be made of soft resin.Therefore, the material can be made of hard synthetic resin. In order to provide a sufficient sealing function, it is necessary to press the container mouth with a considerably strong force, which makes it difficult to plug the lid or remove the frame. If it is made easier to do so, it has the disadvantage that it will not be possible to achieve a sufficient seal.

である。The present invention molds the gripping part and the restraint part as separate parts and then integrates them by fitting them together, so that the gripping part can be made of a hard material and the restraint part can be made of a soft material. , a sealing plug which can fully satisfy the unboxing operation and the sealing function is obtained.

以下本考案の実施例を示す図面について詳述すれば、第
２図、第３図において密栓Ａは把持部１と、控部２と、
締着リング１１とから構成されている。The drawings showing the embodiments of the present invention will be described in detail below. In FIGS. 2 and 3, the seal plug A has a grip part 1, a retaining part 2,
It consists of a fastening ring 11.

把持部１は、頂壁３と、該頂壁周縁から垂設した周壁４

きの段部６を周設して形成されている。The grip part 1 includes a top wall 3 and a peripheral wall 4 hanging from the periphery of the top wall.
It is integrally molded with a hard material such as glass or hard synthetic resin into an arbitrary cross-sectional shape, and a peripheral wall 4 is provided on the lower side.
A perfectly circular fitting tube 5 having a diameter smaller than the outer diameter of the fitting tube 5 is integrally installed vertically, thereby forming a downwardly facing stepped portion 6 at the boundary between the fitting tube 5 and the peripheral wall 4. .

控部２は、底壁７と、該底壁から立設した周壁８とから

・・・を上下方向へ多数個周設して形成されている。The retaining portion 2 is formed integrally with a bottom wall 7 and a peripheral wall 8 standing from the bottom wall into a cup shape and made of an elastic soft material such as soft synthetic resin or synthetic rubber so that the peripheral wall is elastic. At the same time, the peripheral wall 8 is tapered at least on the lower side so that it can easily fit into the mouth 9 of the container B, and the upper side has a
The protrusions 10 are arranged so as to be closely held against the inner wall surface of the mouth portion 9.
It is formed by arranging a large number of ... around the top and bottom in the vertical direction.

締着リング１１は、例えば硬質の合成樹脂又は金属等の
硬質材でその直径が拡大されないように父上記控部２の

定して形成されている。The fastening ring 11 is made of a hard material such as a hard synthetic resin or metal, and its inner diameter is set in advance so that the fastening ring 11 is fitted so as to circumscribe the outer periphery of the proximal end of the retaining portion 2 so as not to increase its diameter. It is formed by

該締着リング下端面は、把持部下端面とほぼ同一平面上

Ａは構成されている。The upper end of the frame 2 circumscribing the fitting cylinder 5 of the gripping part 1 is fitted with an annular recess 12 and a protrusion 13 that can be fitted to the opposing wall surfaces of the two. At the same time, a fastening ring 11 is provided around the outer periphery of the stopper part fitted into the fitting tube 5 as described above, and a protrusion 14 and an annular recess 15 that can be mutually fitted are provided around the opposing wall surfaces of both. The gripping part 1 and the frame part 2 are press-fitted together, and the expansion of the frame peripheral wall 8 is prevented by the fastening ring 11.
The sealing plug A is constructed by winding the fastening ring 11 together and fixing it firmly.

締着リングの下端面は容器口頂面への係合面となし、又
該締着リング下端面よりも下方の栓部部分は容器口部内
への嵌合部とする。The lower end surface of the fastening ring serves as an engaging surface for the top surface of the container mouth, and the stopper portion below the lower end surface of the fastening ring serves as a fitting portion into the container mouth.

は確実に行われることになる。In this case, as mentioned above, since the grip part 1 is made of a hard material, the grip part 1 does not undergo deformation such as twisting or buckling when force is transmitted to the frame part 2 when closing the lid or removing the frame. The frame part 2 can be easily fitted into or removed from the mouth part, and the frame part 2 has an elastic bottomed cylindrical shape, and its upper end part is engaged with the lower outer surface of the grip part 1, and the engaging part A fastening ring 11 is placed on the outer surface, and the lower end surface of the fastening ring and the lower end surface of the grip are placed on substantially the same plane, or the lower end surface of the fastening ring is positioned lower than the lower end surface of the grip, and the fastening ring 11 is wound and tightened. Since the lower end surface of the ring is used as a retaining surface to the top surface of the container, and the stopper portion below the lower end surface of the fastening ring is used as the fitting portion into the container container, the lower end surface of the fastening ring serves as a stopper. Therefore, only the fitting part is fitted into the mouth of the container, and although the lower part of the grip part 1 is not fitted into the fitting part and is hollow, the fitting part is inside the mouth of the container. It fully conforms to the wall surface, and its own restoring force due to elastic contraction due to press-fitting to the mouth part
The mouth is reliably sealed by acting as a close force against the inner wall surface of the mouth.

従って口部内径と嵌合部外径とに多少の誤差があっても
栓使用上差支えなく、その誤差の許容範囲が大である。Therefore, even if there is some error between the inner diameter of the opening and the outer diameter of the fitting part, there is no problem in using the stopper, and the tolerance for this error is wide.

又枠部２は軟質材で形成したにもかがわらず硬質材から

等の実用的効果がある。Although the frame part 2 is made of a soft material, it is firmly integrated with the grip part 1 made of a hard material by fitting into the fitting cylinder 5 and tightening the fastening ring 11 circumferentially. Although they are not separated when the frame is removed, and the grip part 1 and frame part 2 are formed as separate members, they can be easily molded by vacuum forming or the like, and can be assembled together by simply tightening the fastening ring 11. Since it can be easily done, it has practical effects such as being suitable for mass production and being manufactured at low cost.
